Abstract
Official abstract text for this publication.
A storage control apparatus manages a plurality of storage devices which belong to a RAID Logical Unit (RLU) such that data is made redundant between different storage devices, where RAID stands for Redundant Arrays of Independent Disks. If a first storage device fails, a rebuild controller executes a rebuild process to store the same data as recorded in the first storage device in a spare storage device. When the rebuild controller executing the rebuild process has failed in reading out data from a second storage device, a data recovery controller restarts the first storage device, and reads out data to be stored in the spare storage device from the restarted first storage device.
First claim
Opening claim text (preview).
What is claimed is: 1. A storage system comprising: a plurality of storage devices; a storage control apparatus configured to control recording of data in the plurality of storage devices such that the data recorded in the plurality of storage devices is made redundant between different storage devices; and a spare storage device configured to be used in place of any of the plurality of storage devices, wherein the storage control apparatus performs a procedure including:…
